•Generation of coupling files

The amplitude is transformed to FeynArts notation:

mfa = FCToFA[melsimplified] ;

Terms are collected according to momenta:

mfacoll = MomentaCollect[mfa, ParticlesNumber -> 4, PerturbationOrder -> 1] ;

The coupling vectors for the FeynArts model files are generated and saved:

gencoup = GenericCoupling[mfacoll] ; gencoup

{p _ 3 _ μ _ 1, p _ 2 _ μ _ 1, p _ 4 _ μ _ 1, p _ 5 _ μ _ 1}

classcoup = Map[(WriteString["stdout", "."] ; Collect[# // Expand, {_DecayConstant, _CouplingConstant, _SU3D, _SU3F, _SUNDelta}, If[FreeQ[#, _DecayConstant | _CouplingConstant], Simplify[#], #] &]) &, ClassesCoupling[mfacoll], {2}] ;

....

classcoup // LeafCount
